[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Implementation Method 1

[0043] like Figure 2 As shown, the utility model provides a platform reinforcement device, including: a basic structure 5; at least one lower pillar 2, whose bottom end is connected to the basic structure 5; at least one upper pillar 1, whose top end is connected to at least one upper platform beam 201; at least one supporting connection structure 3, the bottom end of the upper pillar 1 and the top end of the lower pillar 2 are connected through the supporting connection structure 3, the lower platform below the upper platform beam 201 is located between the upper pillar 1 and the lower pillar 2, and there is a vibration isolation gap 33 between the lower platform and the upper pillar 1 and the lower pillar 2.

[0044] Among them, an upper platform beam 201 is provided with an upper platform plate 202, thereby forming an upper platform; the lower platform includes a lower platform beam 301 and a lower platform plate 302 provided on the lower platform beam 301. In the embodiment of the utility model, the upper platform beam 201 and the lower platform beam 301 are both concrete beams. Optionally, the upper platform beam 201 and the lower platform beam 301 can also be steel beams. Figure 1 As shown, the upper platform beam 201 and the lower platform beam 301 can be erected on a main support structure 10 such as a support frame and a support wall.

[0045] The platform reinforcement device of the utility model, on the one hand, can reduce the span of the upper platform beam 201 under the support of multiple upper pillars 1, change the natural frequency of the upper platform beam 201, avoid resonance between the upper platform beam 201 and the equipment installed on the upper platform, thereby reducing the vibration of the upper platform beam 201; on the other hand, it can transmit the vibration of the upper platform beam 201 to the foundation structure 5 via the upper pillar 1, the supporting connection structure 3 and the lower pillar 2, and because there is a vibration isolation gap 33 between the lower platform and the upper pillar 1 and the lower pillar 2, it can avoid the vibration from being transmitted to the lower platform and affecting the stability of the lower platform beam 301, thereby ensuring that the equipment installed on the lower platform can operate stably.

[0046] Combination Figure 1 and Figure 2 As shown, the platform reinforcement device of the utility model is particularly suitable for reinforcing the vibrating screen platform 20 of the ore storage tank, so as to avoid the resonance caused by the natural frequency of the supporting beam (i.e., the upper platform beam 201) of the vibrating screen platform 20 being close to the vibration frequency of the vibrating screen 50, thereby reducing the vibration of the upper platform beam 201 of the vibrating screen platform 20, and can transmit the vibration of the upper platform beam 201 of the vibrating screen platform 20 to the basic structure 5, thereby avoiding the structural damage of the upper platform beam 201 of the vibrating screen platform 20 due to vibration, realizing the reinforcement of the upper platform beam 201 of the vibrating screen platform 20, and can also avoid the vibration from being transmitted to the weighing platform 30, thereby ensuring that the weighing device 60 on the weighing platform 30 can operate stably.

[0047] Of course, the platform reinforcement device of the utility model can also be used to reinforce the platforms of other equipment as needed, which can also produce the above-mentioned beneficial effects.

[0048] Specific, combined Figure 2 As shown, the upper support 1 and the lower support 2 can be selected in different sizes, shapes and / or materials according to the reinforcement requirements. In this embodiment, the upper support 1 and the lower support 2 are both circular steel pipe columns with high support strength and easy installation. Optionally, the upper support 1 and the lower support 2 can also be square steel pipe columns. Optionally, the upper support 1 and the lower support 2 can also be a main support structure 10 made of channel steel, H-shaped steel or other steel. And the number of upper support 1, support connection structure 3 and lower support 2 can be set to one or more according to the number of upper platform beams 201 and reinforcement requirements. For example, in some embodiments of the utility model, the number of upper platform beams 201 is multiple, and multiple upper platform beams 201 are arranged in parallel. The number of upper support 1, support connection structure 3 and lower support 2 is correspondingly arranged, and is arranged at intervals along the arrangement direction of multiple upper platform beams 201. The lower platform beam 301 is arranged perpendicular to the upper platform beam 201 in space. When the number of support connection structures 3 is set to multiple, multiple support connection structures 3 are arranged at intervals along the axial direction of the lower platform beam 301.

[0049] Of course, if the stability of the upper platform is to be further improved, the upper platform beam 201 may be provided with a plurality of beams 201 extending in the axial direction thereof (i.e., in the longitudinal direction thereof). Figure 2 A plurality of upper pillars 1, supporting connection structures 3 and lower pillars 2 are arranged at intervals (in a direction perpendicular to the page).

[0050] like Figure 2 As shown, when the installation space below the upper platform beam 201 is limited and the upper pillar 1 cannot be installed directly below the upper platform beam 201, the upper pillar 1 can be connected to the upper platform beam 201 through the conversion beam 4, so that the upper pillar 1 is arranged below the upper platform beam 201. Wherein, when there are multiple upper platform beams 201, multiple upper platform beams 201 are arranged in parallel, the conversion beam 4 is extended along the arrangement direction of the multiple upper platform beams 201 and is located below the multiple upper platform beams 201, and the number of upper pillars 1 is preferably set to multiple, and of course it can also be set to one. In order to improve the stability of the structure, the platform reinforcement device is symmetrically arranged relative to the distribution center of the multiple upper platform beams 201. When the number of the upper platform beam 201 is one, multiple upper pillars 1 are connected to the conversion beam 4. In order to improve the stability of the structure, the platform reinforcement device is symmetrically arranged relative to the central axis of the upper platform beam 201, that is, the center of the conversion beam 4 and the distribution center of the multiple upper pillars 1 are both located directly below the central axis of the upper platform beam 201.

[0051] Combination Figure 3 , Figure 4 as well as Figure 5 As shown, in order to ensure the stability of the connection between the conversion beam 4 and the upper platform beam 201, a connection plate 45 is provided on the top surface of the conversion beam 4. The connection plate 45 has a bottom plate 451 and two side plates 452 arranged opposite to and connected to the bottom plate 451. The bottom plate 451 is fixed to the top surface of the conversion beam 4, and the upper platform beam 201 is inserted between the two side plates 452 of the connection plate 45 and fixedly connected to the inner side surfaces of the two side plates 452. The number of the connection plates 45 can be set to one or more according to the number of the upper platform beams 201. For example, in the embodiment of the present utility model, the number of the connection plates 45 is multiple, and multiple upper platform beams 201 are correspondingly inserted between the two side plates 452 of multiple connection plates 45.

[0052] Specifically, the connecting plate 45 is generally a U-shaped steel plate structure. Mud is poured between the connecting plate 45 and the upper platform beam 201, so that the bottom surface of the upper platform beam 201 and the top surface of the bottom plate 451 are closely fitted, and the two side surfaces of the upper platform beam 201 and the inner side surfaces of the two side plates 452 are closely fitted. The bottom surface of the bottom plate 451 is welded and fixed to the top surface of the conversion beam 4. The conversion beam 4 is generally an H-shaped steel beam structure, including an upper wing plate 42, a lower wing plate 43 and a web 41.

The upper wing plate 42 is welded to the bottom plate 451 of the connecting plate 45, and the lower wing plate 43 is welded to the upper top plate 11 set at the top of the upper support 1. In addition, in order to improve the structural strength of the conversion beam 4, a plurality of beam stiffening plates 44 are also provided on both sides of the web 41 to connect with the upper wing plate 42 and the lower wing plate 43.

[0053] Combination Figure 3 As shown, in order to further improve the stability of the connection between the transfer beam 4 and the upper platform, the outer side surfaces of the two side plates 452 of each connecting plate 45 are also connected to the upper platform plate 202 through a plurality of connecting bolts 46. Specifically, the plurality of connecting bolts 46 are distributed on both sides of the upper platform beam 201. Figure 4 As shown, a fixing plate 47 is disposed on the upper platform plate 202, and the bottom ends of a plurality of connecting bolts 46 pass through the fixing plate 47 in sequence to weld the upper platform plate 202 to the outer side surface of the corresponding side plate 452 below. The fixing plate 47 is a steel plate.

[0054] Of course, if the installation space below the upper platform beam 201 is not restricted by other equipment and the upper support 1 can be installed directly below the upper platform beam 201, the conversion beam 4 can be omitted and the lower support 2 can be directly connected to the upper platform beam 201 through the above-mentioned connecting plate 45 and connecting bolts 46.

The upper support 1 and the lower support 2 are connected by a plurality of tension bolts 32, and the plurality of support members 31 are used to support and limit between the upper support 1 and the lower support 2, ensuring that a vibration isolation gap 33 is formed between the lower platform and the upper bottom end plate 12 of the upper support 1 and the lower top end plate 21 of the lower support 2, so that the vibration of the upper support 1 is transmitted to the lower support 2 through the plurality of support members 31, and is not directly transmitted to the lower platform beam 301.

[0056] Specific, combined Figure 7 , Figure 8 as well as Fig. 9 As shown, a vibration isolation gap 33 is formed between the lower platform plate 302 and the upper bottom end plate 12, and a vibration isolation gap 33 is also formed between the bottom surface of the lower platform beam 301 and the lower top plate 21. The vibration isolation gap 33 is 40mm-60mm, preferably 50mm. The support member 31 is preferably made of angle steel, which has good supporting strength. The top of the support member 31 is welded and fixed to the bottom surface of the upper bottom end plate 12, and the bottom end of the support member 31 is welded and fixed to the top surface of the lower top plate 21. The upper bottom end plate 12 and the lower top plate 21 are both generally square steel plate structures, and four support members 31 are distributed at the four corners of the upper bottom end plate 12 and the lower top plate 21. The four corners of the upper bottom end plate 12 and the lower top plate 21 are provided with a plurality of upper bolt holes 14 and a plurality of lower bolt holes 24 for passing a plurality of tension bolts 32.

[0057] like Fig.10 As shown, in the embodiment of the utility model, a lower bottom end plate 22 is provided at the bottom end of the lower pillar 2, and the lower bottom end plate 22 is connected to the base structure 5 through a plurality of anchor bolt structures.

[0059] Combination Fig.10 and Fig.12As shown, in order to prevent the foundation structure 5 from settling later and failing to provide effective support for the lower pillar 2, in the embodiment of the utility model, the top of the anchor bolt 53 passes through the lower bottom end plate 22 with a reserved length, and the lower pillar 2 can move upward relative to the anchor bolt 53 by the reserved length to form a secondary pouring space between the lower pillar 2 and the foundation structure 5, and the secondary pouring space is used to pour concrete to form a secondary pouring layer 6. When the foundation structure 5 settles later, the clamping nut 54 can be removed or screwed upward by the reserved length, and then the lower pillar 2 is lifted up by the reserved length, so that the gap space formed between the lower bottom end plate 22 of the lower pillar 2 and the foundation structure 5 is used to form a secondary pouring space, and then concrete is poured into the secondary pouring space to solidify to form a secondary pouring layer 6.
